Background: The purpose of this study was to revise and validate the "Individual Child Engagement Record" (ICER), an instrument designed to observe and measure the engagement of children with disabilities in early childhood settings. Method: The ICER was revised with reference to pilot study results and the literature. Inter-observer…

Promoting social interaction among students with severe disabilities and their general education peers has long been a prominent focus of research and policy efforts. We asked 81 educators to evaluate the effectiveness, feasibility, and actual use of 12 intervention strategies for increasing social interaction among high school students with and…

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

The purpose of this article is to describe the processes followed to develop an authentic, reliable and valid play-based assessment of communication-related behaviours in young children with severe disabilities. The Daily Multiple Measurement Instrument (DMMI) was developed to be used based on an intervention package of play activities. The…

When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)

Educational assessment and, more broadly, educational research in the United States have entered into an era characterized by a dramatic increase in the prevalence and importance of test score use in accountability systems. This volume covers a selection of contemporary issues about testing science and practice that impact the nation's public…

This review of 50 social validation research studies involving persons with handicaps concludes that social validation procedures are an appropriate and important component of applied behavior analysis. Discussed are methodological issues, social importance of effects, social significance of goals, social appropriateness of procedures, and…

The use of unconventional interventions in special education is addressed, and teachers are urged to stick with data-based interventions that have empirical evidence supporting their effectiveness. (DB)

The article examines issues related to establishing a rationale for the use of early childhood rating scales and to selecting a rating scale using such criteria as user needs, user friendliness, scale format, score interpretation, reliability, and validity. Methods of establishing the validity of a rating scale are suggested. (Author/DB)

The evaluation of a parent-completed screening system, the Infant Monitoring Questionnaires, found: 86 percent to 91 percent agreement between classifications of infants made using standardized tests and the questionnaires, low under-screening and over-screening rates (0 percent to 11 percent), high inter-observer and test-retest agreement, and…

General/special education secondary teachers (N=183) and nonhandicapped and handicapped students (N=437) were surveyed on perceptions of the importance of social skills in relating to others, relating to adults, and relating to oneself. Discussed are the survey instrument's reliability, importance ratings for skills, and levels of agreement…

This study examined the internal validity and reasons for false positives for the Ten Question Screen (with and without probes), used by community workers in developing nations to assess type and severity of disability. Results support the use of the screen but only if paired with measurements of hearing and visual impairments. (DB)

The paper examines issues, philosophy and guidelines for psychological assessment of the disabled. Focused on are: (1) adjustments in testing procedures and (2) applicability of standard norms with commonly used psychological test instruments for the assessment of ability, interest, and personality. The importance of accurate assessment for…

The article addresses the usefulness of the Peabody Individual Achievement Test (PIAT) in assessing various levels of arithmetic performance. The mathematics subtest of the PIAT is considered in terms of purpose; mathematical abilities subsections (foundations, basic facts, applications); diagnostic testing (the error analysis matrix); and poor…

The personal value of any goal determination process increases when a goal is conceivable, believable, achievable, controllable, measurable, desirable, stated with no alternative, and growth facilitating. A guide is offered for enhancing the value of Individualized Education Programs (IEPs) by elaborating upon these eight elements as crucial parts…
